GTWe propose a shallow XMM survey making contiguous EPIC pointings in areas observed by the AAT 2degree field multifibre spectroscopy system. We propose 18 pointings in total in two AAT fields reaching a flux level of \\sim4\\times 10^{15}\\rm\\ erg cm^{2}\\s^{1} in the 0.52 keV band and detecting at least 350 QSOs and 200 other sources {\\it per {\\rm AAT} field} in this band alone. The sample will provide an excellent database for the study of, {\\it inter alia}, a) QSO hard and softband Xray luminosity functions; b) the average typical QSO spectrum and its evolution; c) the nature of the flatspectrum population implied by hard Xray number counts and d) the contribution of galaxies to the Xray background. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
